Just wondering what you did to check the vacuum lines. My trucks 4wd light stays on for about 30 or so minutes give or take, after I engage the 4wd. Not sure whats going on. All that I know is I need some help with the system. Also would you give me some advice on what do to next? Its a 5.2 with a magnaflow exhaust and a magnaflow high flow cat. I don't have a cold air intake on it yet. What would you reccommend?
I do understand that a throttle body spacer doesn't do much of anything on my truck anyways, but if I do this mod would it completely ruin it if i put the spacer back on? maybe mod the spacer? opinions?
